Re: How to import PostgreSQL 9.2.4 dump to PostgreSQL 9.4.5? - Mailing list pgsql-hackers

Hi guys,

I'm running some test.


However, I'm stuck in restoring a PostgreSQL 9.2.4 dump to PostgreSQL
9.4.5 database.
I'm doing the backup using pg_dump version PostgreSQL 9.2.4 in text
file (SQL dump).
I'm trying to restore it to PostgreSQL 9.4.5 usng psql.

The restoration error message was as below:
 psql:room.sql:41695: invalid command \n
Query buffer reset (cleared).
psql:room.sql:41696: invalid command \n
Query buffer reset (cleared).


The SQL statement in the file as below:
COPY room (id, user_id, partner_id, rm_cr_ts, rm_up_ts, rm_sv_ts,
value, last_dlvrd_to_user, last_dlvrd_to_prtnr, last_seen_by_user,
last_seen_by_prtnr, num_unseen_by_user, num_unseen_by_prtnr,
last_message_id, last_message_ts, legacy_id, legacy_last_message_id,
inserted_at, updated_at) FROM stdin;

I create the room table as below:
CREATE TABLE room (
    id integer NOT NULL,
    user_id character varying(255),
    partner_id character varying(255),
    rm_cr_ts bigint,
    rm_up_ts bigint,
    rm_sv_ts bigint,
    value character varying(255),
    last_dlvrd_to_user bigint,
    last_dlvrd_to_prtnr bigint,
    last_seen_by_user bigint,
    last_seen_by_prtnr bigint,
    num_unseen_by_user integer,
    num_unseen_by_prtnr integer,
    last_message_id integer,
    last_message_ts bigint,
    legacy_id text,
    legacy_last_message_id text,
    inserted_at timestamp without time zone NOT NULL,
    updated_at timestamp without time zone NOT NULL
);


All the servers are Debian 7.8 (Wheezy) with hardware:
- CPU 24 cores
- RAM 128GB
- SSD 128GB


Have anyone try this before?
How to do it properly?


Thanks in advance,
Fattah
